AntiCorrosive Pigments
The ramangwana maitiro mu anticorrosive pigments ndeyekuwana chromate yemahara uye inorema simbi yemahara pigments uye kuenda munzira ye sub-micron uye nanotechnology anti corrosive pigments uye akangwara machira ane corrosion-inonzwa. Rudzi urwu rwemachira akangwara ane mamicrocapsules ane pH chiratidzo kana corrosion inhibitor kana/uye kuzvirapa. Iyo goko reiyo microcapsule inoputsika pasi peyakakosha pH mamiriro. Iyo pH chiratidzo inoshanduka ruvara uye inoburitswa kubva kumicrocapsule pamwe chete necorrosion inhibitor uye / kana kuzvirapa.
Ramangwana ndere 'green tekinoroji' uyezve masangano ehurumende akasiyana atopa gwara mune zvinotevera mirairo:
- OSHA PEL yakurudzira 5 µg/m3 yeCr6+ munzvimbo dzebasa Kukadzi 27, 2006.
- OSHA yakaraira kushambadza PEL itsva. (chadenga PEL ikozvino 20 µg/m3)
- EU Directive 2000/53/EC - Kupera-kwe-Hupenyu Mota: Cr6+, Pb, Cd, Hg yakarambidzwa kubva kumotokari dzakatengeswa mushure meChikunguru 1, 2003.
- California Air Resources Board (CARB) yakabvumidza Airborne Toxic Control Measure (ATCM) yeEmissions yeCr6+ uye Cd kubva kuMota Mota uye Nharembozha Equipment Coatings (Automotive Coatings) Gunyana 21, 2001.
Anticorrosive pigments izvo zvinosimbisa mirau iyi semuenzaniso: Calcium Phosphate; Calcium Borosilicate; Calcium silicagel; Magnesium Phosphate.
